Peach production in the Czech Republic is currently in decline. The major problem is the surplus of old orchards with a limited range of varieties, absence of young orchards, health condition of the trees, and the market environment where the import of foreign fruits is supported. This situation can be solved by the introduction of modern, reliable varieties, which can extend the peach season and meet the requirements regarding the market needs. The degree of PPV occurrence was monitored in a young peach orchard during 2010– 2011. The percentage of infected trees in as well as the intensity of PPV symptoms in two peach varieties „Royal Glory“ and „Symphony“ grafted on seven different rootstocks of Prunus species after the natural infection was evaluated. This paper presents some examples of prospective varieties, lists different pomological groups of prospective varieties, and classifies the varieties in terms of their resistance to plum pox virus (PPV) and late spring and winter frosts. Finally, training systems and fruit-breeding programme in the Czech Republic are briefly characterised.
